In other words the top pulley goes 2.6 revolutions for every revolution on the bottom. Anything that interferes with the blower output (especially inlet restriction) will decrease blower CFM and decrease boost and hp. Let’s stuff a large-by-huge 6-71 supercharger on top of a stock 350 engine that makes a normally aspirated 300 hp. Kennedy’s is a dealer for all the major supercharger and turbocharger brands but recommends the Procharger line! CID*rpm/3,456*(.9) = engine airflow requirement Choose your drive type * Belt (V belt or rib belt) Cog . Out at the peak rpm (6,600 rpm) where the boost level of the centrifugal reached 11.5 psi, the power difference was more than 120 hp (though the roots blower had lost 1 psi there). the thermal efficiency of the supercharger at the boost pressure. Performance Trends Blower Boost Calculator Type in the required information: Blower Belt Ratio Engine Vol. Calculate the amount of air used by the engine at a certain boost pressure. You're going to have to have .030/.035 end gap on the top ring also because it will get pretty hot. Supercharger Boost Calculator ~ Input the Blower Belt Ratio, Engine Volumetric Efficiency Percentage, the Blower Volumetric Efficiency Percentage, the Engine Displacement, Blower Displacement and the Barometric Pressure and the Supercharger Boost Calculator will give you the Blower Boost. Increased air density (cooler, drier, higher barometric pressure) will increase hp, lower air density will decrease hp. There are a few basics to remember. To calculate engine demand in cfm, we first need to calculate engine displacement in cubic feet. This will give you an idea of what happens under boost and also how you should plan your motor for your target altitude whether it is for racing or day to day operation. Anything which increases VE will increase power but decrease boost. This is because at lower blower speeds, the clearances between the blower case and the rotors allows for air “leak-age” with some loss of boost efficiency. Then read across to the right under the boost you want to run and the number in the box will be your "effective" compression ratio. Enter the anticipated blower pressure. You can ROUGHLY estimate max boost as follows.
